（摩擦力）」は、ゴム栓１６の弾性変形力より大き
くなる定性がある。``Problem to be solved by the invention'' In the waterproof connector equipped with a rubber plug of the conventional structure described above, in order to ensure sealing performance, it is necessary to provide a large amount of forcible fitting distance between the rubber plug 16 and the terminal accommodation chamber 8. Therefore, a considerable insertion force is required to insert the terminal 1 with a rubber plug, and since the rubber plug 16 itself is highly elastic in both the radial and axial directions, the insertion force of the terminal 1 +Insertion resistance force (frictional force) of the rubber plug 16 has a qualitative property that it is larger than the elastic deformation force of the rubber plug 16.

がある。 Therefore, the primary locking mechanism of the terminal 1 is provided by the locking portion 11 of the terminal housing chamber 8, and the locking claw 12 of the stopper member 14 attached from the rear of the rubber plug 16 and the locking hole 13 on the terminal housing chamber 8 side are used. In the case of a double locking structure having a secondary locking mechanism for the terminal 1, the stopper member 1
Even if the rubber stopper 16 is pushed back by the rubber stopper 1
6 is easily elastically deformed and the terminal 1 does not move forward, and when the primary locking mechanism is not sufficiently engaged (when the terminal is half-inserted), the terminal 1 is easily elastically deformed and the terminal 1 is not moved forward. There is a problem in that the insertion position of the terminal is not corrected and incomplete locking occurs in which only the secondary locking mechanism of the stopper member 14 acts without the primary locking mechanism functioning, resulting in poor locking of the terminal.

The seal ring is pressed against the inner periphery of the terminal accommodating chamber, the wire insertion hole is pressed against the outer periphery of the wire, and the terminal accommodating hole is pressed from behind the rubber stopper. It has a structure in which a stopper member having a locking mechanism is inserted into the chamber from behind.

することができる。 Therefore, the rubber plug part can be expected to have sufficient elasticity for sealing at the sealing ring on the outer periphery serving as the sealing point and at the inner periphery of the wire insertion hole at the center. The rubber plug has a unique property in which the rigidity in the axial direction is significantly increased due to the inclusion of the rubber plug attachment ring, and when the stopper member is pushed from behind the rubber plug, the rubber plug has unnecessary axial Elastic deformation does not occur, and the terminal integrated with the rubber plug portion can be moved forward to correct a defective terminal that is not fully inserted.

As shown in FIG.
It has a structure in which it is pressed against the outer periphery of the electric wire 9 to make it waterproof. In addition, since the waterproof connector of this embodiment has a double locking structure for the terminal 1, in addition to the one locking mechanism that engages the locking portion 11 on the terminal housing chamber 8 side and the front end portion of the terminal 1, there is also a rubber locking mechanism. Insert the plug part 3 from behind,
A secondary locking mechanism is provided which includes a stopper member 14 that prevents the terminal 1 from retreating by fitting its locking claw 12 into the locking hole 13 of the terminal accommodating chamber 8. Also,
The covering part of the electric wire 9 and the terminal are fixed using the rubber plug part 3.
The terminal 1 is provided with only a gripping part 15 for the bare wire part of the electric wire 9.

できる。 The waterproof connector of the above embodiment has an integrated structure of the terminal and the rubber plug, in which the rubber plug part 3 is formed by embedding the rubber plug attachment ring 2 of the terminal 1. Since the ring ring 2 is included, the seal ring 5 on the outer periphery serves as the sealing point of the rubber plug part 3.
A, 5B and the inner circumferential portion of the wire insertion hole 6 retain sufficient elasticity necessary for sealing in both the axial and radial directions of the rubber plug portion 3, and the portion other than the sealing point has sufficient axial rigidity. Therefore, when the rubber plug part 3 is pushed back by the stopper member 14, the rubber plug part 3 does not undergo unnecessary axial deformation, and the terminal 1 moves forward together with the rubber plug part 3, so that the insertion amount of the terminal 1 can be reduced. When the primary locking mechanism malfunctions due to insufficient engagement, the insertion position of the terminal 1 is corrected and the primary locking mechanism engages with a "snap" and functions normally,
The function of the double locking structure of the terminal can be properly performed.
